" said it was radar jamming?"
As I mentioned earlier that's one of several possible options; some forms of jamming, especially basic "area" noise jamming does produce "spokes" on radar displays and the military do ( or certainly used to do) jamming exercises at times for training purposes but probably/hopefully not on a frequency and/or not with enough energy to significantly interfere with the commercial weather radars in the adjacent airspace..
